You Will Learn

• How to install a hard drive
• How to use diagnostic software
• How to recover lost data on hard drives
• How to apply hard drive troubleshooting skills

3
Installing a Hard Drive

• Set jumpers or DIP switches on the drive
• Physically install an adapter card, cable, and
  drive
• Change CMOS setup
• Partition, format, and install software on the
  drive
• Protect the drive and the PC against static
  electricity

4
Physical Installation of IDE or SCSI Hard Drives

• IDE
• Drive
• 40-pin data cable
• Possibly a kit to make drive fit in larger bay
• SCSI
• Drive
• Cable compatible with host adapter
• Possibly
• External terminator
• Host adapter
• Kit to make drive fit the bay

5
Installing an IDE Hard Drive

• IDE hard drives support up to four IDE devices on
  the same system
• Four possible setups for each device
• Primary IDE channel, master device
• Primary IDE channel, slave device
• Secondary IDE channel, master device
• Secondary IDE channel, slave device
• Place fastest devices on primary channel and
  slower devices on secondary channel

6
Installing an IDE Hard Drive

• Take precautions
• Have a good bootable disk or Windows 9x rescue
  disk
• Read all documentation and check the setup of the
  computer
• Visualize the entire installation
• Understand the meaning of each DIP switch or
  jumper on the drive

Precautions for Working with Hard Drives

• Handle the drive carefully
• Do not touch exposed circuitry or chips
• Drain static electricity from your body and from
  the package containing the drive
• If you must set it down, place the drive
  component-side up on top of the static-protective
  package on a flat surface
• Do not place the drive on the computer case cover
  or on a metal table

Informing Setup of the New Hard Drive

• Setup for hard drives less than 528 MB
• Older BIOS setup assumes use of CHS mode
• New BIOS select CHS mode or normal mode
• Setup for large-capacity hard drives
• Two ways BIOS relates to large capacity drives
• LBA
• Large mode

20
Informing Setup of the New Hard Drive

• When BIOS does not support large-capacity hard
  drives
• Let the BIOS see the drive as a smaller drive
• Upgrade the BIOS (best solution)
• Upgrade the entire system board
• Use software that interfaces between the older
  BIOS and the large-capacity drive (e.g., Disk
  Manager by OnTrack, SpeedStor by Storage
  Dimensions, EZ-Drive by StorageSoft)
• Use an adapter card that provides the BIOS to
  substitute for system BIOS (e.g., Promise
  Technology, Inc.)

21
A Note on Moving a Hard Drive or Changing BIOS

• Backup up the data on the hard drive before you
  move it to avoid potential problems with
• Lost data
• Inability to access the drives data
• Different translation methods for LBA mode
• Dont change options in setup unless you are sure
  of what you are doing

22
Partitioning the Hard Drive

• Partition table
• Written at the very beginning of a hard drive
• Describes number and location of all partitions
• Identifies the boot partition
• A drive must have one primary partition and can
  have one extended partition
• The drive boots from the primary partition
• The extended partition can be subdivided into
  several logical drive partitions
